Just bought an iPhone 17 – device won’t recognize portable monitor for screen mirroring

I just got an iPhone 17 today, and when I try to connect it to my Selfie Monitor Screen SYNCO XView M4, it always shows 'searching' but doesn’t recognize any device. However, when I connect the monitor to my old iPhone 11 or iPad Air M3, it works fine. Can anyone tell me how to fix this problem? Could it have something to do with the new iOS 26? By the way, the monitor doesn’t require Wi-Fi or Bluetooth to connect.

I’ve also tried resetting my network settings, restarting my phone, switching airplane mode on and off, and even resetting the device, but none of these fixed the problem.

The Synco product description now has a "Firmware Update for iPhone 17 Lineup". There are two files to download: the firmware update itself (intended for the monitor to run, not for your computer or your iPhone to run), and an instruction sheet.

Looks like you'll need a computer, a USB flash drive, and a powered USB-C dock to help update the firmware on the monitor. (If you have a USB-C dock for your computer system, you could temporarily unplug it from your computer, and its accessories, for use in updating the phone.)

i just checked details of the monitor. Looks like it uses this P2P technology, allowing connection without wifi or bluetooth.

I have the same issue and can pair the device with bluetooh, but when I go to screen mirroring the device does not show up.

I’m experiencing the same issue. I was able to update the firmware but I still cannot mirror the screen with my iPhone 17 pro (I’m able to do it with my 16).

How did you update the firmware? I’ve been trying for 2 days and no luck. I’ve followed all the steps posted
